PS4 firmware 2.0 Masamune has introduced a pretty nasty problem which is rest mode, but happily there’s another one on the way which will hopefully fix it. Sony has acknowledged general issues with the firmware update when reports first arose, but in a tweet today they acknowledged the rest mode problem in particular, saying a fix is inbound. https://twitter.com/PlayStation/status/529846820751806464 The rest mode issue is quite serious as it requires a hard reset to recover from, which can be very risky, you may end up wiping system data or worse bricking the console. Best to switch your console off completely between sessions until the next firmware update. Source Sony Via Twitter.
